Books / literature on JSP/servets/beans

Hi,
Can some one suggest good books/web sites which talks about using JSP/Servlets/Beans in one application
Thanks
Raj

A good site I can think of is "Theserverside.com".

Sample jsp servlet bean (MVC) code

We want to look into the JSP/Servlet/Bean area for our next project. We wish to understand the technology and as such want to hand build simple applications, and as such do not want to use JDeveloper just yet.
We have searched and searched for suitable material but cannot anywhere find a sample application that :
A. Lists contents of a databse table
B. Each item in trhe list is a link to a page that allows that item, to be edited.
C. A new item can be added.
D. Uses the MVC model of JSP/Servlet and bean (preferably with no custom tags)
There are examples that are too simplistic and do not cover the whole picture. Having spent over 100 GBP on books lately, only to be disappointed with the examples provided, we need to see some sample code.
The samples provided by Oracle are too simplistic. They should really have provided ones built around the EMP and DEPT tables.
Anyone know where we can get hold of this sample code.

At the risk of sounding really dumb the examples are just too complex. There does not appear to be anywhere on the web where I can find a simple JSP/servlet/bean example of the type I described. There is enouigh material describing each individual component, but what I need is an example to cement the ideas, but the ones suggested are too much for a newbie. Even the much vaunted Pet Store thingy causes my eyes to glaze over.
I dont expect anyone to have written something with my exact requirements, but surely to goodness there must be something that:
1. On entry presents a search form on a table (e.g. EMP)
2. On submission list all rows in EMp matchiung the criteria.
3. The user can either click the link 'Edit' which opens up a form dispalying the row allowing the user to edit and save the changes, or click the 'New' button to show a blank form to create a new EMP.
All this via a Controller servlet, with the database logic handled by a java bean, and all the presentation done via JSP.
To me this is the most obvious and instructive example of this technology, but after days of trawling the web, and looking through a number of books, I cannot find such a thing.
CGI with Perl DBI/DBD was a breeze to work with compared to this stuff ..... maybe ASP with SQL/Server would be a more fruitful use of time.

How to convert the source code in JSP,HTML&BEANS into executable files?

Sir,
We are developing one s/w product in JSP,HTML&BEANS.Now we are in the implementation phase.During the time of Installation,without copying our source code in the customer's site I want to copy the executable files of the entire source codes? Is it possible in JSP,HTML&BEANS?

In theory you can do it even with JSP but the you will be unable to run it on the standard JSP engine. :-)
From other hand, all critical logic should be in the Java Beans or at least in custom tags but not in the JSP code. Then you can protect that code and leave JSP open because there is nothing to steal or break.

WLS 8.1 sp1 with Struts 1.1 JSP with bean tag won't compile

          Hello,
          We are currently porting our application which uses struts 1.1 to WLS 8.1 sp1
          from another app server. Everything seems to deploy correctly and pages which
          use struts tags appear to compile and run fine. However, the pages with struts
          <bean:define> tags are not compiling.
          Example JSP Code:
          <bean:define id="userForm" name="userForm" scope="session" toScope="page" type="UserFormBean"/>
          <% if (userForm.hasUserData()) {hasUser=true;} %>
          WLS Console Output:
          ..jsp_servlet\_jsp\_sailor\__home.java:493: cannot resolve symbol
          symbol : variable userForm
          location: class jsp_servlet._jsp._sailor.__home
          if (userForm.hasUserData()) { //[ /jsp/sailor/home.jsp; Line: 38]
          When I look at the JSP's parsed java code (__home.java:493) I find that nowhere
          in the class is the variable userForm declared.
          Is this a bug in WLS? Does anyone know of a workaround?
          Thanks,
          Scott

JSP- Servlet-- Bean-- JSP how to implement

I have problem.
My JSP will take a emplyee id .
Now I want to show all the values regarding that employee in a JSP(JSP form) from the DB(Oracle).
So Iam planning like
JSP-->Servlet-->Bean-->JSP
So my doubts are.
1. Is it correct approach
2.If it is correct then which part of the flow connects to DB and stores the value before putting to JSP.
Iam using Tomcat 4.31

What you are probably proposing is an MVC design pattern. I wonder if u have heard of the struts framework. Sruts uses MVC design pattern wherein the servlet u are talking about acts as a controller(C) and the bean acts as the model(M) .The JSPs present the view(V). Hence the name MVC.
Your approach is right. First get the employee ID from the jsp and get the corresponding data from database(This logic u implement in the servlet). Then save the fetched data in a bean so that the result jsp can fetch data from it.
Now this is not a strict MVC approach.
Learn more about struts. It presents a much more cleaner solution.

Do all JSP/Java bean webapps need an xml file?

Hi all,
I have a jsp/ java bean webb application. This is being run on Resin at
Lunarpages.
The site has been shut down due to 'class-loader' not found. I was told it
was causing problems for other java users on the server.
I realise this is limited information but any insight would be welcome.
This is our first JSP / java bean web app.
Also if anyone could tell me briefly the purpose of an xml document in a JSP/Java bean webapplication I would greatly appreciate it.
Thanks in advance
Regards
Jim

Hi there,
Thanks for the reply.
Our application allows people to purchase wedding pictures online. It ran locally on resin we then had to change all the relative file paths in order to deploy it on lunarpages.
Lunarpages use resin also.
We had the application tested and working on Lunarpages for the last week .This morning they sent us a message saying they had shut our JSP pages down as our application was causing problems for other java users. errant code unknown element ' class-loader' .
Not too much help from lunarpages...
thanks

How can write string in jsp on beans..

Hello.
My English ability very poor sorry....
I am developing jsp using beans..
I want to see value on beans....
but I can't see....
I want to check my values...
plz help me....
how can I view my String , int... on the beans....

Write a "getter" method for each variable you want to be able to read in the JSP.
example:
public class yourBean
// ... some code, contructor, etc...
private String yourVariable;
public void setYourVariable(String s)
yourVariable = s ;
public String getYourVariable()
return yourVariable ;
You can retrieve the value in your jsp with any of these ways:
1) use the <jsp:getProperty> tag
2) <%= yourBean.getYourVariable() %>
3) <% String s = yourBean.getYourVariable() %>
}

Please recommend IDE for JSP and Beans

Hi guys,
I am looking for a decent IDE to work with JSP and Beans. I have tried JBuilder which has too much going on at the same time and I find it to be an overkill for what I am doing; I find NetBeans kind of irritating. I develop web applications, hence I dont need any GUI stuff for beans.
Just looking for something that will enable me to rapidly develop beans as a support system for JSP pages and at the same time, it should provide good support for coding JSP pages. Little bit of management functions wont hurt either, but are not required. I dont mind if I have to pay for the IDE. Any recommendations?

I like Eclipse for Java Development, and I use the MyEclipse plug-in for J2EE development.
There is a free J2EE plug-in (Lomboz) but I'd much rather pay the $29.99/year for MyEclipse. It's been perfect for me.

Jsp-servlet-bean problem

Please help!
I have a servlet controller, a javabean for the data and a jsp for the view.
I cannot get the jsp using
<jsp:useBean id="pList" class="bbs.PostListCommand" scope="request" />
to access the bean data
However, when I access the bean in this way
<%@ page import="bbs.PostListCommand" %>
// html
<% bbs.PostListCommand postList = null;
synchronized(session){
     postList = (bbs.PostListCommand) session.getAttribute("PostListCommand");
     if (postList == null){ %>
          <H1>Nothing in request scope to retrieve ....</H1>
          <P>
<%     }
     else{ %>
          <TABLE border="1">
// etc
� it works
Does anyone know why the <jsp:useBean> tag does not find the bean
I have installed tomcat 4.18 and set the environmental variables etc.
Directory structure is
E:\Tomcat41\webapps\examples\WEB-INF\jsp          for jsp�s
E:\Tomcat41\webapps\examples\WEB-INF\classes\bbs     for bean and servlets
Thanks in advance for any help.
Chris

GrayMan - Thanks for your help.
Let me explain my problem in more detail ...
Background:
I have some servlet experience, but I am new to jsp - so sorry if this seems trivial to you ...
I have a book called bitter java by bruce tate from manning.com . I am trying to get the chapter 3 examples to work
There are three files
PostListCommand          the bean
PostListController     the servlet
PostListResults          jsp
And a new test file � PostListResults version 2 with scriptlet code to access the bean.
There are a couple of typos in the downloaded source files, but nothing that causes the main problem of not being able to access the bean data.
Program flow
Servlet instantiates new bean
Bean � gets data from db
Servlet passes bean to jsp with a forward
Jsp outputs data
I have put the files in the directories �
E:\Tomcat41\webapps\examples\WEB-INF\jsp          for jsp�s
E:\Tomcat41\webapps\examples\WEB-INF\classes\bbs     for bean and servlets
The complete source code for each file is given below.
1 I have checked the db access � that�s ok
2 I have also checked reading the bean data back in from the request scope and printing out the results from within the servlet.- ok
3 I can access the data through a scriptlet (PostListResults version 2), but not with the original PostListResults which uses <jsp:useBean>
thanks in advance, chris

Need help with JSP - Session Bean scenario

I have massive problems with a simple JSP <--> Statefull Session Bean scenario with Server Platform Edition 8.2 (build b06-fcs)
What I do is generating a Collection in session bean returning it to JSP
and giving the List back to Session Bean.
A weird exception happens when giving the List back to Session Bean
(see Exception details below)
The same code runs without any trouble on Jboss Application Server 4.0.3
Any help would be great!
Please see code below

Hi,
I have found a way out by passing the reference of my EJB in the HttpSession object and using it inside the javabean..

Column Not found error while trying to access databse through JSP+Java Bean

I am trying to acees MS Access 2003 db through JSP using Tomcat 5.0.28.The code for accessing the databse is incorporated in the bean.The jsp only calls the particular method of the bean .
Code for Java Bean:
package ActiveViewer;
import java.sql.*;
import java.util.*;
public class CompanyBean
Connection con;
ResultSet rs=null;
Statement st;
     public CompanyBean(){}
     public void connect()
     try
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
System.out.println("Here4");
con=DriverManager.getConnection("jdbc:odbc:activeviewer","","");
     System.out.println("Here1");
     catch (ClassNotFoundException e)
     System.out.println("Could not locate driver.");
catch (SQLException e)
System.out.println("An SQL Exception has occured :: "+e);
     e.printStackTrace();
     catch (Exception e)
System.out.println("An unknown Exception has occured :: "+e);
     e.printStackTrace();
public void disconnect()
     try
     if (con!=null)
con.close();
     catch (SQLException e)
System.out.println("An SQL Exception has occured :: "+e);
     e.printStackTrace();
public ResultSet select(String username)
if(con!=null)
     try
st=con.createStatement();
     rs=st.executeQuery("select * from company where username='" + username + "'");
catch (SQLException e)
System.out.println("An SQL Exception has occured :: "+e);
     e.printStackTrace();
catch (Exception e)
System.out.println("An Exception has occured while retrieving :: "+e);
e.printStackTrace();
else
System.out.println("Connection to database was lost.");
return rs;
The code for JSP that uses the above bean is:
<%@ page language="java" import="java.sql.*,ActiveViewer.* " contentType="text/html"%>
<jsp:useBean id="conn" scope="session" class="ActiveViewer.CompanyBean" />
<html>
<body>
<% String username=request.getParameter("username");
String password=request.getParameter("password");
System.out.println("username:"+username);
System.out.println("password:"+password);
conn.connect();
ResultSet rs=conn.select(username);
System.out.println("Below select ");
while (rs.next())
String dbusername=rs.getString("username");
     String dbpassword=rs.getString("password");
     if(dbusername.equals(username) && dbpassword.equals (password))
{ %> out.println("OK");
          <% }
else { %>Invalid Username and / or Password.
<br>Clickhere to go back to Login Page.
<% }
} %>
</body>
</html>
I get the following error:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: Column not found
though the database is not int he same folder as the jsp, the DSN is set correctly to pint to the db location.The jsp does print in stdout file:
Here4 (from connect method above)
Here 1 (from connect method above)
Below Select (from jsp)
This means that the jsp does connect to db but it gives the above error.Also the field name also matches that in the database and data is present in the db too.
All other things like creating package for bean,incorporating the packakage are done.
Can someone please help me with their precious advice?

U're getting this error because there is no field called 'password' in ur database, the field in ur database is named 'cpassword' and not 'password'. So change the statement rs.getString("password"); to rs.getString("cpassword");

Package everywhere the same.
Have commented some of the code, because i was trying to debug, but just couldn't figure it out.
Tnx in advance.

put your bean in a different package from servlet and include this
package in your servlet like
import yourbeanpackage.yourbean
and then create object of bean and use it

Urgent help is needed - JSP & Java beans

Hi,
I am getting the following problem when trying to interact with Javabeans from JSP (DB I use is Cloudscape) :
An exception occurred while interacting with the guestbook database.
The error message was:
Cannot create bean of class proj.beans.UserDataBean
Please try again later
The problem probably occurs in following line:
status = guestData.checkUser(userName,emailName);
where guestData represents a Javabean class.
The strangest thing is that sometimes, suddenly, the program is working OK without this Error Message but when it occurs I don't know the reason and how to solve it.
Please advise...
Thanks a lot.

Can you copy the entire stack trace and post it? It would probably help.

Problem with JSP using bean packaged in jar file

Hi,
          I am trying to use a java bean in a jsp file. The java bean is packaged
          into a jar file. I am getting class not found compilation error. If the
          bean remains to be a seperated class file, everything work well.
          Does anyone know how I can use bean in a jar file within jsp , i.e. to
          allow the bean to be found during compilation ?
          Thanks,
          Terence.

Jacek,
          Thanks for replying.
          My JSP's are just files in my document root . However, I found a solution to
          my
          problem. That is to have the jar file defined in my weblogic.class.path. I may
          have missed some files in my original jar file which causes my problem.
          Mayby I should package everything into a web application for deployment. That
          will be my next step.
          Thanks anyway.
          Terence.
